Answer:
A. the graph increases, then decreases
Step-by-step: just took the test:)
Answer:
A.
Sample 1 mean: 6.375
Sample 2 mean: 6.375
Sample 3 mean: 6.625
B.
Range of sample means: 0.25
C.
The first and last boxes should be checked, as they are true.
Step-by-step explanation:
To calculate the mean you must add all of the numbers together and then divide the sum by the quantity of numbers. Ex: 3+7+8+3+7+9+6+8 = 51.
51/8 = 6.375.
We have to compare diameters and arrange them in order smallest to greatest
We can see units for option A and B are in square inches so they represents area. So first we will find diameter from area using formula

so for choice (A) area is given as
. So plug this in A place in formula and then solve for radius r




3731.76 = r
So screw A will have
inches
Similarly for choice (E) area is 
so again plug in formula





2.13201 = r
So screw E will have
inches
So diameters of all screws are as follows:
Screw A: 7463.52 inches
Screw B: 1.5 inches
Screw C:
inches
Screw D: 0.25 inches
Screw E: 4.26402 inches
Comparing all numbers 7463.52, 1.5, 1.875, 0.25, 4.26402 we can see that smallest number is 0.25, then comes 1.5, then 1.875 and then 4.26402 and then 7463.52
So order from least to greatest will be screw D (0.25), B(1.5), C(1.875), E (4.26402), A (7463.52).
So thats the order D,B,C,E,A and the final answer
